Failed my emissions test today due to the fact that my check-engine light was on due to overboosting. They told me I need it cleared before I can pass my test. My question is can I just take this to my mechanic to fix this or do I need to take her in to a Mitsu dealership? Thanks in advance.

The bigger question is, why were you overboosting? Did you get a tune and someone forgot to disable the error code?

Go to autozone or like store and have them clear it..its free. Then go back and re take your sat's or emissions w.e. it is.

make sure you drive it around enough to put the ecu in the "ready state" once you do this.

Unless you are friendly with your AUTOZONE store, they are no longer supposed to clear codes. They would do the scan, but will not clear it for you.

You can get a cheap OBDII reader/clearer at Harbor Freight. Worth the money, since with these cars, I seem to need it regularly.

You can also buy a tactrix cable and clear them that way. That way, you aren't wasting money and can tune or monitor your car.

or pm a nice evo member in your area to maybe help to read and clear your code.

i guess my question is why waste time in going if you saw your CEL on?

Werd!

And even after the code is cleared you need to drive it for a while like mentioned so the ECU can get back in the ready state.

How about just disconnecting the battery for a few minutes then driving it around a bit to get everything back to readiness state?

OP said he has a mechanic so yes, go to your mechanic. Now next time you are going to get any car smogged, make sure it doesn't have a big yellow light that says "Check Engine".

If you go back to the same smog station, the rep will probably be on to you and check for more things than just the light. If your overboosting issue is affecting your emmissions negatively, he is for sure going to catch that way past a simple CEL.

Also, he is more likely to look for aftermarket parts to fail you on the visual inspection portion.

That is, of course, if he isn't a "cool person".

Thank you, was beginning to wonder if my post was invisible

because most people dont understand all the checks the car does before it reverts back to a ready state.... there are many conditions that need to be passed such as cold starts, etc, etc. All the checks could be taken care of in 15 miles, or it could take 100.... its hit or miss really, unless ofcourse you know exactly the tests that need to pass to put it in readiness state
